HAT-MACHINE.

The object of our invention is to provide y a simple and easily operatedmachine which, by the employment to all portions of a hat body upon ablock, which pressure can be varied or regulated at the will of theoperator, and then instantly relieved. We accomplish this ob- `ect bymeans w the fiuid medium to the fabric or material of the hat body, thusavoiding any liability of injuring it. j l

A' further object of the invention is to provide a machine which pulls,blocks, and presses the hat body, all at one operation.

With lthese and other invention consistsy in the improvements which wewill .now proceed to describe and claim.
